What if you do a make clean before cmake the new installation? Or just remove all the installed and compiled files before new installation?

I managed to successfully install this software before, however, I recently needed to make changes to activate some optional settings. Therefore, I recompiled gate with fag changes from OFF to ON for a few settings. However, the compilation failed. I then tried to restore to the original basic Gate installation using the commands shown below: cmake -DCMAKE_INSTALL_PREFIX=/usr/local/gate_v7.1-install -DGATE_DOWNLOAD_BENCHMARKS_DATA=ON /usr/local/gate_v7.1 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/gate_v7.1-install -DGATE_DOWNLOAD_EXAMPLES_DATA=ON /usr/local/gate_v7.1 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/gate_v7.1-install -DGATE_USE_ECAT7=OFF /usr/local/gate_v7.1 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/gate_v7.1 -DGATE_USE_LMF=OFF /usr/local/gate_v7.1 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/gate_v7.1 -DGATE_USE_OPTICAL=ON /usr/local/gate_v7.1 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/gate_v7.1 -DGATE_USE_GPU=OFF /usr/local/gate_v7.1 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/gate_v7.1 -DGATE_USE_GEANT4_UIVIS=ON /usr/local/gate_v7.1 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/gate_v7.1 -DGEANT4_USE_SYSTEM_CLHEP=OFF /usr/local/gate_v7.1 <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> make -j4 make install </blockquote> However, the installation keeps failing at CMAKE stage. Can someone please let me know what it is that I’m not doing correctly? I desperately need to get this problem sorted out. Your help will be very much appreciated.
