Added basic VERSION mode for pkg-config mode of cmake [WIP] (!2017) · Merge requests · CMake / CMake

Now we can invoke cmake like this:

cmake --find-package -DNAME=Qt5Core -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=VERSION

This will return the version of Qt5Core module if found (like 5.10.1)

Also added VERSION parameter to pass to find_package.

While testing with many modules like Boost, SDL, X11,... I got several errors.

First with Boost I get 106600 as version while I would expect 1.66.0 which is printed out when doing a simple find_package(Boost REQUIRED)
Secondly on many packages I get an errors like:

FindThreads only works if either C or CXX language is enabled

CHECK_FUNCTION_EXISTS needs either C or CXX language enabled

Could we fix this?
