Hi Regina, You need to update as I'm currently testing on a 5-modality 3-D data set and I discovered that the rigid initialization wasn't being performed properly in the ants multivariate I think you want CPACK_SET_DESTDIR, then make sure CMAKE_INSTALL_PREFIX is how you want it before you run cpack. We’ll need to do some setup to get started. The prefix can be relocated at install time using the DESTDIR mechanism explained in the CMAKE_INSTALL_PREFIX variable documentation. It's cross-compilation that doesn't work. Now run the cmake executable or the cmake-gui to configure the project and then build it with your chosen build tool.. Then run the install step by using the install option of the cmake command (introduced in 3.15, older versions of CMake must use make install) from the command line. Relative paths are installed into DESTDIR/${project’s CMAKE_INSTALL_PREFIX} where DESTDIR is set to the temporary staging area.

I'm not saying there isn't a common use case for changing the install directory on the fly -- clearly there is judging by the number of votes -- I'm just fairly new to CMake and curious when this problem comes up. But do remember to place it BEFORE PROJECT(< project_name>) command, otherwise it will not work! The CMakeLists.txt should never install anything outside of CMAKE_INSTALL_PREFIX. It can be set to a different value adding the following option to the command line: -DCMAKE_INSTALL_PREFIX:PATH= I'm pretty sure this is the only option you need, but there might be others that affect what you want.

The prefix can be relocated at install time using the DESTDIR mechanism explained in the CMAKE_INSTALL_PREFIX variable documentation.

In my build system I have the Wii(U) libraries outside of the ${DEVKITPPC} folder and want to specify the folder via -DCMAKE_PREFIX_PATH, but line 44 in wut-toolchain.cmake hardcodes a CMAKE_FIND_ROOT_PATH, so the PREFIX_PATH doesn't work anymore (because the ROOT_PATH is prefixed to the PREFIX_PATH I guess? CMake Warning (dev) at CMakeLists.txt:34 (find_package): Findxlnt.cmake must either be part of this project itself, in this case adjust CMAKE_MODULE_PATH so that it points to the correct location inside its source tree. The details of this project are not important. It does work if you are building for Ubuntu on Ubuntu. Then the installation will not work.
