Hello. I would like to know what profiling tools I should use in order to get the performance analysis of CMake project. The project is written in several languages, as a result there are several control files to inspect. Is it possible to get the cpu/mem usage info of the whole project?  
The second part is to profile the functions used in specific unit/feature test .c files. As the build is generate by CMake which profiler should I use for functional performance analysis?

Update: I would like to link google perf tools to Cmake project. Could you please help me with that?

There are various tools which can do this, but they are platform-specific. Instruments on macOS and `valgrind` on Linux would be places to start looking.

Again, this is linked to the platform (or compiler). `gperf` is fine with GCC or Clang AFAIK.

It looks like there’s a `.pc` file for `gperftools`. I would recommend using [`FindPkgConfig`](https://cmake.org/cmake/help/latest/module/FindPkgConfig.html) to find and use it.
