Hello:

When I build with cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/programs/mylibvmi -DENABLE_KVM=ON -DENABLE_XEN=OFF -DENABLE_BAREFLANK=OFF and then run make -j6, there are so many undefined references errors:

After many tries, I found that this code (line 33 in [ROOT]/CMakeLists.txt) is doing the bad thing: string(REGEX REPLACE "-l" "" GLIB_LDFLAGS ${GLIB_LDFLAGS}) when i comment out this line, everything works fine.

I don't know if there will be some other problems, so I made this issue.

I tried something different(alongside this). I simply switched the version of CMake (from 3.25.1 which i was using and getting the same error) to 3.2.0, due to this thread .

TLDR:- It seems to be a CMake 3.21+ related issue
