Hi Kent,
I believe it's not "empty quotes" that disables the install command, it's
the empty string. So you should not escape the quotes:
#######################
# Default behavior is to NOT install library, empty quotes should disable
install
set( libxxx_inst_comm INSTALL_COMMAND "" )
# Build the library as an external project
ExternalProject_Add( libxxx
SOURCE_DIR ${PROJECT_SOURCE_DIR}/src
${libxxx_inst_comm}
)
#######################
