When i tried this using SUDO, it did not work correctly...

However ...

When i logged in as ROOT and tried it it worked...

Go Figure.

And ... when i did it with SUDO, i got the CMAKE_ROOT error as well.

And ... when i did a CMake --version it gave me the old version, two point something.

When completed as ROOT, the error went away, and the version showed as: cmake version 3.12.3

LOG IN AS ROOT!

Thanks for sharing the steps @1duo

How do we uninstall or cleanup if we have installed cmake via the above steps

thanks for sharing @1duo. i did find two cmake paths and find CMAKE_BIN in R points to /usr/bin/cmake. but the include library shows /usr/local/bin. after changing the name in /usr/bin/cmake. it works. you are awesome!

make uninstall incase something goes wrong

yum uninstall cmake is you already have version 2.8, it will remove it.

"CMake Error: Could not find CMAKE_ROOT !!!"
Having Error. However, after rebooting the CentOS system. It works well.

Have an error with the install command

collect2: error: ld returned 1 exit status
make[2]: *** [Utilities/cmcurl/CMakeFiles/LIBCURL.dir/build.make:88: Utilities/cmcurl/LIBCURL] Error 1
make[1]: *** [CMakeFiles/Makefile2:1533: Utilities/cmcurl/CMakeFiles/LIBCURL.dir/all] Error 2
make: *** [Makefile:163: all] Error 2

Any idea to fix it?

Thanks in advance
