Cannot make on Ubuntu

[generalizedeigenvector]

When doing cmake .. I get the following error:

-- The C compiler identification is GNU 5.4.0 -- The CXX compiler identification is GNU 5.4.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- Compiling on Unix -- Could NOT find CHOLMOD (missing: CHOLMOD_INCLUDE_DIR CHOLMOD_LIBRARIES) -- A library with BLAS API not found.

 "/usr/lib/x86_64-linux-gnu/libGL.so"

but this file does not exist. Possible reasons include:

• The file was deleted, renamed, or moved to another location.

• An install or uninstall procedure did not complete successfully.

• The installation package was faulty and contained

  "/usr/lib/x86_64-linux-gnu/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake"

  but not all the files it references.

I have a file called "/usr/lib/x86_64-linux-gnu/libEGL.so" - perhaps I just need to rename it? Also tried to apt-get Qt5 anew but this did not help.

Did you find a solution?

Installing suitesparse fixed this issue for me on Ubuntu 20.04: sudo apt-get install -y libsuitesparse-dev

For Mac OS users: brew install suitesparse
