Re: [CMake] How to find/run external host executables when using cross compiling
This is a case for using the ExternalProject module!
You have a top level 'SuperBuild' whose job it is to find all the
prerequisites for the actual project build. Then it configures and builds
it.
This means that the tricky configuration is handled by CMake, instead of
working it out yourself by hand.
The Superbuild can be part of the project's source tree. The simplest
method is to make a SuperBuild subdirectory, and put in a CMakeLists.txt
something like this:
project(MySuperBuild)
include(ExternalProject)
# find all the prerequisite tools
ExternalProject_Add(MyActualProject
DOWNLOAD_COMMAND ""
BINARY_DIR MyActualProject-build
SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/.. # SuperBuild is subdir of
source directory
CMAKE_ARGS# all the arguments to
configure your project.
-DPERL_EXECUTABLE:STRING=${PERL_EXECUTABLE} # for example
INSTALL_COMMAND ""# deployment not handled
by install

[CMake] How to prevent .lib file to be installed?
Hi,
I'm creating a 'plugin' DLL and want to prevent the associated .lib file
to be installed (cause its not being used).
My Install code looks like this now:
install (TARGETS ${target}
DESTINATION plugins
COMPONENT plugins
)
and it installs both a .DLL and a .lib file. Any simple fix?

If it is a plugin, i.e. it is only opened using dlopen() or the Windows
equivalent that I forgot the name, and never linked against, don't use SHARED
but MODULE in the add_library() call.
