CMAKE_FIND_NO_INSTALL_PREFIX
----------------------------
Ignore the :variable:`CMAKE_INSTALL_PREFIX` when searching for assets.
CMake adds the :variable:`CMAKE_INSTALL_PREFIX` to the
:variable:`CMAKE_SYSTEM_PREFIX_PATH` by default. This variable may be set
on the command line to control that behavior.
Set :variable:`CMAKE_FIND_NO_INSTALL_PREFIX` to TRUE to tell find_package not
to search in the :variable:`CMAKE_INSTALL_PREFIX` by default. Note that the
prefix may still be searched for other reasons, such as being the same prefix
as the CMake installation, or for being a built-in system prefix.

CMake Error at do_test.cmake:2 \(find_package\):
By not providing "FindNoPrefix.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "NoPrefix",
but CMake did not find one.
Could not find a package configuration file provided by "NoPrefix" with any
of the following names:
NoPrefixConfig.cmake
noprefix-config.cmake
Add the installation prefix of "NoPrefix" to CMAKE_PREFIX_PATH or set
"NoPrefix_DIR" to a directory containing one of the above files. If
"NoPrefix" provides a separate development package or SDK, be sure it has
been installed.
