How to build a program with 2 different values of a variable in CMake

Question

I\'ve recently ported my Qt project from qmake to CMake. My main program contains a value which depends on a #define directiv

Answer 1

Another way could be:

mkdir two directory
buildflavor1
buildflavor2

In the first sub directory run:

cmake -DFLAVOR=OPTION1 ..

in the second run:

run cmake -DFLAVOR=OPTION2 ..

So two executable with same name with different compilation flag with is own feature .o and so on.
