If I’m not mistaken, you should be able to change the install prefix using the CMAKE_ARGS option in the Configure step. This is my ExternalProject_Add I use to download third party stuff. Things enclosed by @ are replaced at configure time by correct names/URLs.
```
ExternalProject_Add(
@TP_PACKAGE_NAME@
GIT_REPOSITORY @TP_PACKAGE_GIT_REPOSITORY@
GIT_TAG "master"
GIT_PROGRESS TRUE
UPDATE_COMMAND ${GIT_EXECUTABLE} pull
LOG_DOWNLOAD ON
LOG_CONFIGURE ON
LOG_BUILD ON
INSTALL_DIR "@TP_PACKAGE_INSTALL_DIR@"
CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=<INSTALL_DIR> -DCMAKE_CXX_FLAGS='-g'
)
```

I am in the process of adding ExternalProject_Add commands to my program
and I find them to work okay, except when they get to the install step.
Once they reach the install, they fail as they don't have super user
access to install in /usr/local/, which is where I want them.
How do you work around this with ExternalProject_Add?
