Is there a good and easy way to build CMake
projects using Premake
and incorporate (link, include, etc.) them?
Premake doesn't have native facilities to incorporate CMake projects in their scripts.
You might still run application from premake/Lua if wanted.
I would just build and install 3rd party using their build system (unless you convert their script to premake's one).
Then regular project usage just have includedirs
/libdirs
/links
possibly defines
to be set. so use them as any system library.
