[regression] Could NOT find coordgen with RDK_INSTALL_STATIC_LIBS=OFF

[vedranmiletic]

This is on FreeBSD 14 amd64 with Clang 16. I use the following configuration:

% cmake -B build -S . -DCMAKE_CXX_FLAGS='-DBOOST_STACKTRACE_GNU_SOURCE_NOT_REQUIRED=1' -DRDK_INSTALL_STATIC_LIBS=OFF

The error printed by CMake during configuration is:

-- coordgen include dir set as coordgen_INCLUDE_DIRS-NOTFOUND
-- coordgen libraries set as 'coordgen_LIBRARIES-NOTFOUND'
-- Could NOT find coordgen (missing: coordgen_INCLUDE_DIRS coordgen_LIBRARIES)
Downloading https://github.com/schrodinger/coordgenlibs/archive/v3.0.2.tar.gz...
CMake Error at External/CoordGen/CMakeLists.txt:90 (target_compile_options):
Cannot specify compile options for target "coordgen_static" which is not
built by this project.

With RDK_INSTALL_STATIC_LIBS=ON configuration works fine. If I use Release_2024_03 branch (Release_2024_03_1 tag) instead of current master a087cfd, it works fine.

I bisected the issue. The first bad commit is 9367e20.
