[CMake] emulating `make check' behaviour

[Asmodehn Shade]

Hello,

In my case I am using a simple variable BUILD_TESTS in the CMake build to generate or not the tests targets.
after that :

> ccmake
> make
> ctest
 
There is a problem though, but not that important for me :
I need to rerun ccmake to change the value for the BUILD_TESTS variable.
But I dont mind, I rarely do coding the library project and the test project at the same time.
Switch mode : ccmake
Test mode : make && ctest
Lib mode : make && ctest

So that works for me ;) This will solve your 1), but not your 2) (maybe you can have only one main test target called 'test' or 'check' ?)

Good luck ;)
