Detect if files are overridden in the installation directory

Question

I'm configuring a CMake project from source and build and install it with make , ie,

$ ls
./build/  ./source/
$ cd build/
$ cmake ../source/
[...]
$ make
[...]
$ make install
[...]

I noticed now that the project is badly configured in that it contains numerous files with the same name that get overridden in the installation directory, eg, /usr/local/include/mystring.h gets written to more than once by make install .

Is there a systematic way to detect if files are overridden within the same project?

Answer 1

Well, you can wrap install() calls into your own function, which would store all installed files in cache list variable and check for existing item before actually call install() .

You may also check ${PROJECT_BINARY_DIR}/install_manifest.txt file - maybe it would contain duplicates in your case.
