<title>cmake-generator-expressions(7) — CMake 3.26.6 Documentation</title>
<location>https://cmake.org/cmake/help/v3.26/manual/cmake-generator-expressions.7.html</location>
<excerpt>citeturn0search0 [wordlim: 200] Crawled: 2.9 years ago; When using `add_custom_command()` or `add_custom_target()`, use the `VERBATIM` and `COMMAND_EXPAND_LISTS` options to obtain robust argument splitting and quoting. ... Most of the expressions in this section are closely associated with the `cmake_path()` command, providing the same capabilities, but in the form of a generator expression. ... New in version 3.14: The `...` may be a semicolon-separated list of paths, in which case each path is converted individually and a result list is generated using the shell path separator (`:` on POSIX and `;` on Windows). ... See the `cmake-compile-features(7)` manual for information on compile features and a list of supported compilers. ... Changed in version 3.26: When encountered during evaluation of Transitive Usage Requirements, typically in an `INTERFACE_*` target property, lookup of the `tgt` name occurs in the directory of the target specifying the requirement, rather than the directory of the consuming target for which the expression is being evaluated.

Generator expressions can be nested:
    
    target_compile_definitions(tgt PRIVATE
      $&lt;$&lt;VERSION_LESS:$&lt;CXX_COMPILER_VERSION&gt;,4.2.0&gt;:OLD_COMPILER&gt;
    )
    

The above would expand to `OLD_COMPILER` if the `CMAKE_CXX_COMPILER_VERSION` is less than 4.2.0.

## Whitespace And Quoting¶

Generator expressions are typically parsed after command arguments. If a generator expression contains spaces, new lines, semicolons or other characters that may be interpreted as command argument separators, the whole expression should be surrounded by quotes when passed to a command. Failure to do so may result in the expression being split and it may no longer be recognized as a generator expression.

When using `add_custom_command()` or `add_custom_target()`, use the `VERBATIM` and `COMMAND_EXPAND_LISTS` options to obtain robust argument splitting and quoting.
    
    # WRONG: Embedded space will be treated as an argument separator.
    # This ends up not being seen as a generator expression at all.
    add_custom_target(run_some_tool
      COMMAND some_tool -I$&lt;JOIN:$&lt;TARGET_PROPERTY:tgt,INCLUDE_DIRECTORIES&gt;, -I&gt;
      VERBATIM
    )
    
    
    # Better, but still not robust. Quotes prevent the space from splitting the
    # expression. However, the tool will receive the expanded value as a single
    # argument.
    add_custom_target(run_some_tool
      COMMAND some_tool &quot;-I$&lt;JOIN:$&lt;TARGET_PROPERTY:tgt,INCLUDE_DIRECTORIES&gt;, -I&gt;&quot;
      VERBATIM
    )
    
    
    # Nearly correct. Using a semicolon to separate arguments and adding the
    # COMMAND_EXPAND_LISTS option means that paths with spaces will be handled
    # correctly. Quoting the whole expression ensures it is seen as a generator
    # expression. But if the target property is empty, we will get a bare -I
    # with nothing after it.
    add_custom_target(run_some_tool
      COMMAND some_tool &quot;-I$&lt;JOIN:$&lt;TARGET_PROPERTY:tgt,INCLUDE_DIRECTORIES&gt;,;-I&gt;&quot;
      COMMAND_EXPAND_LISTS
      VERBATIM
    )
    

Using variables to build up a more complex generator expression is also a good way to reduce errors and improve readability. The above example can be improved further like so:
    
    # The $&lt;BOOL:...&gt; check prevents adding anything if the property is empty,
    # assuming the property value cannot be one of CMake&#39;s false constants.
    set(prop &quot;$&lt;TARGET_PROPERTY:tgt,INCLUDE_DIRECTORIES&gt;&quot;)
    add_custom_target(run_some_tool
      COMMAND some_tool &quot;$&lt;$&lt;BOOL:${prop}&gt;:-I$&lt;JOIN:${prop},;-I&gt;&gt;&quot;
      COMMAND_EXPAND_LISTS
      VERBATIM
    )
    

A common mistake is to try to split a generator expression across multiple lines with indenting:
    
    # WRONG: New lines and spaces all treated as argument separators, so the
    # generator expression is split and not recognized correctly.
    target_compile_definitions(tgt PRIVATE
      $&lt;$&lt;AND:
          $&lt;CXX_COMPILER_ID:GNU&gt;,
          $&lt;VERSION_GREATER_EQUAL:$&lt;CXX_COMPILER_VERSION&gt;,5&gt;
        &gt;:HAVE_5_OR_LATER&gt;
    )
    

Again, use helper variables with well-chosen names to build up a readable expression instead:
    
    set(is_gnu &quot;$&lt;CXX_COMPILER_ID:GNU&gt;&quot;)
    set(v5_or_later &quot;$&lt;VERSION_GREATER_EQUAL:$&lt;CXX_COMPILER_VERSION&gt;,5&gt;&quot;)
    set(meet_requirements &quot;$&lt;AND:${is_gnu},${v5_or_later}&gt;&quot;)
    target_compile_definitions(tgt PRIVATE
      &quot;$&lt;${meet_requirements}:HAVE_5_OR_LATER&gt;&quot;
    )
    

## Debugging¶

Since generator expressions are evaluated during generation of the buildsystem, and not during processing of `CMakeLists.txt` files, it is not possible to inspect their result with the `message()` command. One possible way to generate debug messages is to add a custom target:
    
    add_custom_target(genexdebug COMMAND ${CMAKE_COMMAND} -E echo &quot;$&lt;...&gt;&quot;)
    

After running cmake, you can then build the `genexdebug` target to print the result of the `$&lt;...&gt;` expression (i.e. run the command `cmake --build ... --target genexdebug`).

Another way is to write debug messages to a file with `file(GENERATE)`:
    
    file(GENERATE OUTPUT filename CONTENT &quot;$&lt;...&gt;&quot;)

## Generator Expression Reference¶

Note

This reference deviates from most of the CMake documentation in that it omits angular brackets `&lt;...&gt;` around placeholders like `condition`, `string`, `target`, etc. This is to prevent an opportunity for those placeholders to be misinterpreted as generator expressions.

$&lt;IN_LIST:string,list&gt;¶
    

New in version 3.12.

`1` if `string` is an item in the semicolon-separated `list`, else `0`. It uses case-sensitive comparisons.

$&lt;JOIN:list,string&gt;¶
    

Joins the list with the content of `string` inserted between each item.

$&lt;REMOVE_DUPLICATES:list&gt;¶
    

New in version 3.15.

Removes duplicated items in the given `list`. The relative order of items is preserved, but if duplicates are encountered, only the first instance is preserved.

$&lt;FILTER:list,INCLUDE|EXCLUDE,regex&gt;¶
    

New in version 3.15.

Includes or removes items from `list` that match the regular expression `regex`.

### Path Expressions¶

Most of the expressions in this section are closely associated with the `cmake_path()` command, providing the same capabilities, but in the form of a generator expression.

For all generator expressions in this section, paths are expected to be in cmake-style format. The $&lt;PATH:CMAKE_PATH&gt; generator expression can be used to convert a native path to a cmake-style one.
If `path` has no filename component (i.e. `$&lt;PATH:HAS_FILENAME&gt;` returns `0`), `path` is unchanged.

See cmake_path(REPLACE_FILENAME) for more details.

$&lt;PATH:REMOVE_EXTENSION[,LAST_ONLY],path&gt;
    

New in version 3.24.

Returns `path` with the extension removed, if any.

See cmake_path(REMOVE_EXTENSION) for more details.

$&lt;PATH:REPLACE_EXTENSION[,LAST_ONLY],path,input&gt;
    

New in version 3.24.

Returns `path` with the extension replaced by `input`, if any.

See cmake_path(REPLACE_EXTENSION) for more details.

$&lt;PATH:NORMAL_PATH,path&gt;
    

New in version 3.24.

Returns `path` normalized according to the steps described in Normalization.

$&lt;PATH:RELATIVE_PATH,path,base_directory&gt;
    

New in version 3.24.

Returns `path`, modified to make it relative to the `base_directory` argument.

See cmake_path(RELATIVE_PATH) for more details.

$&lt;PATH:ABSOLUTE_PATH[,NORMALIZE],path,base_directory&gt;
    

New in version 3.24.

Returns `path` as absolute. If `path` is a relative path (`$&lt;PATH:IS_RELATIVE&gt;` returns `1`), it is evaluated relative to the given base directory specified by `base_directory` argument.

When the `NORMALIZE` option is specified, the path is normalized after the path computation.

See cmake_path(ABSOLUTE_PATH) for more details.

#### Shell Paths¶

$&lt;SHELL_PATH:...&gt;¶
    

New in version 3.4.

Content of `...` converted to shell path style. For example, slashes are converted to backslashes in Windows shells and drive letters are converted to posix paths in MSYS shells. The `...` must be an absolute path.

New in version 3.14: The `...` may be a semicolon-separated list of paths, in which case each path is converted individually and a result list is generated using the shell path separator (`:` on POSIX and `;` on Windows). Be sure to enclose the argument containing this genex in double quotes in CMake source code so that `;` does not split arguments.

`$&lt;$&lt;CONFIG:DEBUG&gt;:FOO_EXTRA_THINGS&gt;`).

To have the expected result (i.e. `FOO_EXTRA_THINGS` if config is `Debug`), it is required to evaluate the output of `$&lt;TARGET_PROPERTY:foo,CUSTOM_KEYS&gt;`:
    
    add_custom_target(printFooKeys
      COMMAND ${CMAKE_COMMAND} -E
        echo $&lt;TARGET_GENEX_EVAL:foo,$&lt;TARGET_PROPERTY:foo,CUSTOM_KEYS&gt;&gt;
    )
    

### Escaped Characters¶

These expressions evaluate to specific string literals. Use them in place of the actual string literal where you need to prevent them from having their special meaning.

$&lt;ANGLE-R&gt;¶
    

A literal `&gt;`. Used for example to compare strings that contain a `&gt;`.

$&lt;COMMA&gt;¶
    

A literal `,`. Used for example to compare strings which contain a `,`.

$&lt;SEMICOLON&gt;¶
    

A literal `;`. Used to prevent list expansion on an argument with `;`.

### Deprecated Expressions¶

$&lt;CONFIGURATION&gt;¶
    

Configuration name. Deprecated since CMake 3.0. Use `CONFIG` instead.</excerpt>

Pass a scalar multi-config flag to the copy script.

CMAKE_CONFIGURATION_TYPES is a semicolon-separated list. The command list later expands unquoted into add_custom_target, so this value can split -DEP_MULTI_CONFIG=$<BOOL:...> and cause generator-expression parsing to fail. Compute EP_MULTI_CONFIG as 0 or 1 at configure time.

Review comment at @cmake/onnxruntime_trt_rtx_ep.cmake at line 201:
Compute a scalar multi-config flag at configure time in the runtime-command
setup, then pass that value as EP_MULTI_CONFIG instead of embedding
CMAKE_CONFIGURATION_TYPES in a generator expression. Keep the flag 1 when
CMAKE_CONFIGURATION_TYPES is set and 0 otherwise.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr

Move the device/stream check ahead of IsCudaUnifiedMemoryDevice(device).

When use_device_io is true and device is empty, the initializer reaches the CUDA lookup before the constructor body checks !device. The constructor can therefore fail before it throws the intended std::invalid_argument.

The CPU OrtRunner example is not reachable as described. HasDeviceIo() requires a non-empty device and a valid stream, so CPU callers pass use_device_io=false. The public TensorBuffer constructor still permits a direct call with an empty device and explicitly attempts to reject it.

Review comment at @common/ort_session.cpp around lines 929 - 935:
Update the TensorBuffer constructor so it validates the device and stream before
calling IsCudaUnifiedMemoryDevice; initialize use_unified_memory_ safely, then
assign its CUDA unified-memory result only after validation, preserving the
disable_uma condition.
