cmake build error on CentOS Stream 10

[leafok88]

I tried building version 3.3.6 with PCRE2 integration. The newly added CMakefile works well on Debian 13 with default switches.
However, it didn't work on CentOS Stream 10. The error message was reported as below.

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
LIBEV
LIBMBEDCRYPTO
LIBMBEDTLS
LIBPCRE2
LIBSODIUM
LIBUDNS
...
CMake Generate step failed. Build files cannot be regenerated correctly.

I checked the libev-devel rpm package and found that it does not provide libev.a. That is different from correpsonding Debian package.

The workaround I found is to set WITH_STATIC=OFF.

Triaged — same root cause as #3028: with WITH_STATIC=ON (default), distros shipping no static .a (CentOS Stream 10, FreeBSD 15) fail at find_library. Needs a graceful fallback to shared. Labeling bug to investigate.
