Then change ${GLUT_LIBRARY} to ${GLUT_LIBRARIES} in this line

[tomichec]

Got the same issue. It would be nice to include the required change into the main branch.

[FengZecheng-zj]

Got the similar issue, thank u

[ngrigri]

Got the similar issue!

To solve the problem I changed in the CMakeLists.txt file the line:
set(GL_LIBS ${OPENGL_LIBRARIES} ${GLUT_LIBRARY} )
to
set(GL_LIBS ${OPENGL_LIBRARIES} ${GLUT_LIBRARIES} )

Install Medit using a script!

cd /tmp 
git clone https://github.com/ISCDtoolbox/Medit.git
cd Medit 
sed -i 's/GLUT_LIBRARY}/GLUT_LIBRARIES}/g' CMakeLists.txt
mkdir build 
cd build 
cmake ..
make
make install

I found this solution by consulting the cmake findGLUT document.

Is it possible to modify the CMakefilelists.txt in this way?

Thank you.
