Why is qmake reqd.?

[aicynide]

I've qmake v.5.15.5 installed

[aicynide]

I tried cmake -D VERBOSE_CONFIGURE=ON -D STACKTRACE=OFF -DGUI=OFF -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=off -Dstatic_runtime=on -DCMAKE_INSTALL_PREFIX="${PREFIX}" also

Getting error:
CMake Warning:
Manually-specified variables were not used by the project:

static_runtime
