[CMake] ExternalProject_Add with flexible install commands

[Knox, Kent]

Hi Petr~

Thanks for your reply.


These set statements do not appear to work.  Either the command 'installs' the dependency, or an error pops up.


set( rocblas_INSTALL_COMMAND INSTALL_COMMAND "" )
--> this installs the dependency

set( rocblas_INSTALL_COMMAND INSTALL_COMMAND " " )
--> /bin/sh: 1:  : not found

set( rocblas_INSTALL_COMMAND INSTALL_COMMAND """" )
--> CMake Warning (dev) in CMakeLists.txt
--> Argument not separated from preceding token by whitespace.

Kent

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}
  )
#######################
