[CMake] Build, Make Install for multiple machines - Guidelines for Success

[B00083603 Michael O Brien]

Hi all,


I have to build OpenCV on multiple machines and I was wondering if the following was possible and advisable or should I use a different method? I'm still learning about the cmake,make, make install way of software installation


Environment

All the machines (vms) have access to the same shared storage and are all are Ubuntu 14.04

On vm1: run "cmake" on the files stored on the shared storage with the configuration I need then run "make -j$(nproc)" before using "make install" to install OpenCV

On vm 2 to vm n: Can I just run make install (assuming all the required software is already installed) or would I be advised to run "cmake" and "make -j" commands again?


Also is there any issues (file locks for example) about running the required commands in parallel on multple vms pointing to the same source or would I be advised to run the commands in serial (vm by vm)?


Finally can I point "make install" to the directory where cmake created the makefile (apologies if this isn't the correct term, but where cmake did its work) so I can script the" make install" from outside the build directory for a slightly cleaner script
