Hi Rob:

Here is what I suggest you use:

INSTALL_COMMAND ${INSTALL_COMMAND}

where for the Unix-like case (Linux, Mac OS X, Cygwin,
MinGW-w64/MSYS2, etc) I recommend you set the INSTALL_COMMAND variable to
something like

${ENV_EXECUTABLE} PATH=${EPA_PATH} ${EPA_PARALLEL_BUILD_COMMAND} install

where ENV_EXECUTABLE is the Unix env command, PATH is set
appropriately for that command, and EPA_PARALLEL_BUILD_COMMAND is
typically "make -j4".  Of course, this logic is currently only suitable for
the Unix case, but once I extend my own epa_build project to use MSVC, I
plan to set the INSTALL_COMMAND variable to whatever is appropriate
("nmake install"?) for that case.

Hope these ideas help.

Alan
