I really want to know what the meaning if the INSTLOCATION in cmake ../ -DCMAKE_INSTALL_PREFIX=INSTLOCATION , how can I find what it is and where I install the ngsolve.
And when I type cmake ... -DCMAKE_INSTALL_PREFIX=/usr, the output always is :
CMake Error: The source directory "/home/kaipeng/ngx/ngsxfem/build/..." does not exist.
Specify --help for usage, or press the help button on the CMake GUI.
I am really need help. Thank you very much!!!!!!
