cmake: fix CMakeLists.txt on Linux

CMakeLists.txt didn't follow the grammar of `set`, and it will fail when
setting `USE_VCPKG` off on non-Windows platforms.

When the platform is Linux, the Makefile adds `compat/linux/procinfo.o`
to `COMPAT_OBJS`, but the CMakeLists.txt didn't add
`compat/linux/procinfo.c` to `compat_SOURCES`. It would cause linkage
error.
