If it builds with CMake, then just give it these arguments:
INSTALL_DIR ${CMAKE_BINARY_DIR}/install
CMAKE_ARGS
-DCMAKE_INSTALL_PREFIX=<INSTALL_DIR>
and leave off the INSTALL_COMMAND, accepting the default install command
that ExternalProject already uses. That should work everywhere.
The thing you're trying to do would work if you did it like this, without
the double quotes:
INSTALL_COMMAND cp
${CMAKE_SOURCE_DIR}/contrib/blas/blas_LINUX.a ${CMAKE_BINARY_DIR}/
But obviously, that will only work where there's a "cp" command, and on
Linux, since the blas_LINUX.a file probably only works on Linux. (And it
generally doesn't work to simply copy library files around as an install
step...)
HTH,
