gtest.h not found on Mac using Conda

[joansola]

Compilation error gtest/gtest.h file not found.

I install my packages using mamba which is a wrapper over conda.

Here's my setup using mamba (with conda would be the same):

mamba create -n manif
mamba activate manif
mamba install eigen ceres-solver gtest autodiff make

The build setup using cmake

mkdir build
cd build
cmake --install-prefix=/Users/xxxx/mambaforge/envs/manif ..

then with ccmake I activate testing and examples. This is the ccmake setup:

see that all deps are found, including gtest.

Then compiling fails:
