When building with cmake 3.22.1, the build fails with the following
errors:
/bin/ld: dataplot.cpp:(.text+0x17): undefined reference to `glutInit'
/bin/ld: dataplot.cpp:(.text+0x62): undefined reference to `glutDisplayFunc'
/bin/ld: dataplot.cpp:(.text+0x6d): undefined reference to `glutMainLoop'
/bin/ld: ../../lib/libkshark-plot.so.2.0.2: undefined reference to `glutInitWindowPosition'
/bin/ld: ../../lib/libkshark-plot.so.2.0.2: undefined reference to `glutInitDisplayMode'
/bin/ld: ../../lib/libkshark-plot.so.2.0.2: undefined reference to `glutInitWindowSize'
/bin/ld: ../../lib/libkshark-plot.so.2.0.2: undefined reference to `glutCreateWindow'
/bin/ld: ../../lib/libkshark-plot.so.2.0.2: undefined reference to `glutSetOption'
The reason is this cmake commit:
https://gitlab.kitware.com/cmake/cmake/-/commit/f90d15458a9a98180fcc95158f2ab5d2b1ad3152,
which changes how the glut library is searched for. Specifically,
pkg-config is newly tried before other methods.
When pkg-config finds the library it doesn't set GLUT_LIBRARY variable
used by kernelshark, but only GLUT_LIBRARIES, as mentioned in the
official documentation:
https://cmake.org/cmake/help/v3.22/module/FindGLUT.html
Therefore, we should switch to using the documented variable.
I also tested this change with CMake 3.21.2 (before the mentioned
commit) and it works.
