IMHO the .pro file should be fixed to take CXXFLAGS from the environment (and
use sane defaults if the environment defines nothing), e.g. like this:
isEmpty(CXXFLAGS) {
CXXFLAGS = $$(CXXFLAGS)
}
isEmpty(CXXFLAGS) {
debug {
CXXFLAGS = -Os -g
} else {
CXXFLAGS = -Os -s -fomit-frame-pointer
}
}
QMAKE_CXXFLAGS_DEBUG = $$CXXFLAGS -Wno-non-virtual-dtor $$PKGCONFIG_CFLAGS
QMAKE_CXXFLAGS_RELEASE = $$CXXFLAGS -Wno-non-virtual-dtor $$PKGCONFIG_CFLAGS
(This example, taken from a real program, also shows how to add mandatory flags
after the ones from the environment.) Then all you have to do is set CXXFLAGS
like with autotools-based programs.
