I am trying to install Openfoam 5 on a centos 7 box. I followed the steps on the wiki pages with the following commands:

cd /share/apps
mkdir OpenFOAM
cd OpenFOAM/
wget "http://dl.openfoam.org/source/5-0" -O OpenFOAM-5.0.tgz
wget "http://dl.openfoam.org/third-party/5-0" -O ThirdParty-5.0.tgz 
tar -xzf OpenFOAM-5.0.tgz
tar -xzf ThirdParty-5.0.tgz
mv OpenFOAM-5.x-version-5.0 OpenFOAM-5.0
mv ThirdParty-5.x-version-5.0 ThirdParty-5.0
cd ThirdParty-5.0
mkdir download
wget -P download https://www.cmake.org/files/v3.9/cmake-3.9.0.tar.gz
wget -P download https://github.com/CGAL/cgal/release...AL-4.10.tar.xz
wget -P download https://netix.dl.sourceforge.net/pro...1_55_0.tar.bz2
tar -xzf download/cmake-3.9.0.tar.gz
tar -xJf download/CGAL-4.10.tar.xz
tar -xjf download/boost_1_55_0.tar.bz2

cd ..
sed -i -e 's/\(boost_version=\)boost-system/\1boost_1_55_0/' OpenFOAM-5.0/etc/config.sh/CGAL
sed -i -e 's/\(cgal_version=\)cgal-system/\1CGAL-4.10/' OpenFOAM-5.0/etc/config.sh/CGAL
echo "alias of50='source /share/apps/OpenFOAM/OpenFOAM-5.0/etc/bashrc $FOAM_SETTINGS'" >> $HOME/.bashrc
source ~/.bashrc
of50
cd $WM_THIRD_PARTY_DIR
wget "https://raw.github.com/wyldckat/scri.../master/getGcc"
wget "https://raw.github.com/wyldckat/Thir...s/makeBinutils"
wget "https://raw.github.com/wyldckat/Thir...ls/getBinutils"
chmod +x get* make*
./getGcc gcc-4.8.5 gmp-5.1.2 mpfr-3.1.2 mpc-1.0.1

wmRefresh
./getBinutils
./makeBinutils gcc-4.8.5
wmRefresh
#change version of cmake to 3.9.0 in makeCmake
./makeCmake

./makeCGAL

At the last command, ./makeCGAL, I get an error that cmake: no such file
I opened makeCGAL and added the full path of the cmake instead of the cmake command only. Then I got another error which says can not find GMP.

It seems that the paths are not set correctly. Any idea about that?

So， have you solved it yet? I come up with the same problem.

Even if you compile CGAL in headers-only mode, it still seems to require gmp and mprf development headers. One of the first things you can do would be to disable CGAL. Edit the etc/config.sh/CCAL file to indicate 'none'. Refresh the environment and continue to build. Leaving out CGAL will only remove the foamy mesher, which not many people use anyhow.

However, I would suggest using a new version of OpenFOAM. Since you are using CentOS-7, you could use the copr build of OpenFOAM-v1912 or OpenFOAM-v2006:
https://develop.openfoam.com/Develop...ompiled/redhat

This should save you a considerable amount of time.
