[CMake] Added option to link with tcmalloc library (#2602)
Added option to link with tcmalloc library.
This should help debug memory leaks.
Usage:
1. install google-perf-tools package
```
sudo apt-get install google-perftools
```
2. Enable linking with tcmalloc library:
```
cmake -DENABLE_TCMALLOC=ON ...
```
This option just adds `-ltcmalloc` to `synfig` and `synfigstudio` binaries.
3. Build binaries and enable heap profiling:
```
env HEAPPROFILE=synfig ./synfig ...
```
This should create `synfig.00xx.heap` files in current folder while running.
More details about tcmalloc options here:
https://gperftools.github.io/gperftools/heapprofile.html
4. Install visualizer dependencies (gv, graphviz):
```
sudo apt install graphviz gv
```
5. Comparing profiles:
```
google-pprof --gv --base=synfig.0002.heap ./synfigstudio synfig.0004.heap
```
This will show where memory is allocated.
