how to modify the install-path without running the configure script/cmake again
build-system, cmake, configure, makefile
Solution
CMake generated makefiles support the DESTDIR coding convention for makefiles. Thus you can override the default installation location by setting the `DESTDIR` variable upon invoking make:
$ make install DESTDIR=/opt/local
There is no need to re-run CMake.
Problem
I am working on a project which takes considerable time to build (10-15) minutes. I have recompiled to verify if there is a compilation error. Now I want to change the install directory so that I have a new version of executable with the new changes. Is there a method to just modify the install path so that the 'make install' installs to a new location rather than the old one?
