[CMake] SUBSTRING - STRING - shorten a string variable

[Sören Freudiger]

Hello

Following problem:

 

My CMakeList.txt file is somewhere like:

E:/LBM_subversion/source/topology/amr3d/lbmd3q19/singlephase/testcases/RCF/a
ll_in_one

 

Now I want to have only the substring:

E:/LBM_subversion/source

 

Is it possible to get last string with the help of CMAKE_CURRENT_SOURCE_DIR?
I just want to know the position of “source”.  Thus I can shorten the string
stored in CMAKE_CURRENT_SOURCE_DIR very easy. I do not always  know the path
behind source/


 

Best SirAnn
