[Cmake] Out of source build

[Zennard Sun]

Hi Andy,
    Thank you for all of your help so far.   I have yet another question 
relating to your previous solution.  I have A.cc B.cc and C.cc all in 
home/z/libFrame.  I wanted to make an out-of-source build like in your 
example so I created a seperate directory called home/z/lib-Sol.  I've 
tried the following in the CMakeLists.txt in lib-Sol:

AUX_SOURCE_DIRECTORY(home/z/libFrame LIB_SOURCE_FILES) 
ADD_LIBRARY(foo STATIC LIB_SOURCE_FILES)

versus:

ADD_LIBRARY(foo home/z/libFrame/A.cc home/z/libFrame/B.cc 
home/z/libFrame/C.cc)

The first solution does not give me an out of source build.  The object 
files are produced in libFrame rather than in lib-Sol.  The second 
solution gives me the correct out of source build and creates the object 
files in libFrame.  Since the sources in that directory may change, I 
would like to use the first solution.  Do you have any ideas?


Thanks,
Zennard Sun
