Documentation of CMake / CPMFindPackage cross-platform incompatibilities?

[aral-matrix]

After getting a working CMakeLists.txt file to pull in dependencies from either local installed packages (CPM_LOCAL_PACKAGES_ONLY) or remote packages (CPM_DOWNLOAD_ALL) on my flavour of Linux (Debian 12/13), I understand that some of the code does not correctly pull in dependencies on Windows. Examples that seem to fail (I can't test this myself) are quoted below.

My question is: Is there a comprehensive list of portability-breaking functions of CMake? Ideally so that I can search it for CPMFindPackage and find those issues that concern this specific function?

Relevant project is here (this specific commit):
troldal/OpenXLSX@e1f0589

• it seemingly does not build with option(OPENXLSX_ENABLE_LIBZIP "Enable using libzip" ON)
