[CMake] temporary build directory for header files

[Mike Jackson]

configure_file(InputFile OutputFile  [COPYONLY] [ESCAPE_QUOTES] [@ONLY])

The Input and Output files have to have full paths. This command
replaces any variables in the input file referenced as ${VAR} or @VAR@
with their values as determined by CMake. If a variable is not
defined, it will be replaced with nothing. If COPYONLY is specified,
then no variable expansion will take place. If ESCAPE_QUOTES is
specified then any substituted quotes will be C-style escaped. The
file will be configured with the current values of CMake variables. If
@ONLY is specified, only variables of the form @VAR@ will be replaces
and ${VAR} will be ignored. This is useful for configuring scripts
that use ${VAR}. Any occurrences of #cmakedefine VAR will be replaced
with either #define VAR or /* #undef VAR */ depending on the setting
of VAR in CMake


You could try that and copy the file where ever you need it. You could
also use the "include_directories" to add  /root/subproject1/ to the
include directories.
