Google Colab colmap script not working ("FileNotFoundError: [Errno 2] No such file or directory: 'colmap'")

[JavierUrenaPhDProjects]

Hello so Im trying to create my own dataset with the google colab notebook: https://colab.research.google.com/gist/kwea123/f0e8f38ff2aa94495dbfe7ae9219f75c/colmap_colab.ipynb#scrollTo=d9ryuCQt2hEv

First, I have trouble installing COLMAP, getting this error:

CMake Error at cmake/FindFLANN.cmake:91 (message):
Could not find FLANN
Call Stack (most recent call first):
CMakeLists.txt:95 (find_package)

After following all the steps and reach the "Run COLMAP!" cell it just says "no such file or directory: colmap'' (supposedly because it did not install well). I've seen other similar issues like #152 or #147 but they are not clearly explained nor exactly my problem. Is there maybe something else to take into consideration?

Thanks
