Make SPIRV_TOOLS_INSTALL_EMACS_HELPERS a CMake option. Otherwise I get a variable-defined-but-not-used error.

# Install a script for use with the auto-compression feature of emacs(1).
|
|
# Upon loading a file with the .spv extension, the file will be disassembled
|
|
# using spirv-dis, and the result colorized with asm-mode in emacs. The file
|
|
# may be edited within the constraints of validity, and when re-saved will be
|
|
# re-assembled using spirv-as.
|
|
|
|
# It is required that those tools be in your PATH. If that is not the case
|
|
# when starting emacs, the path can be modified as in this example:
|
|
# (setenv "PATH" (concat (getenv "PATH") ":/path/to/spirv/tools"))
|
|
#
|
|
# See https://github.com/KhronosGroup/SPIRV-Tools/issues/359
|
|
|
|
# This is an absolute directory, and ignores CMAKE_INSTALL_PREFIX, or
|
|
# it will not be found by emacs upon startup. It is only installed if
|
|
# both of the following are true:
|
|
# 1. SPIRV_TOOLS_INSTALL_EMACS_HELPERS is defined
|
|
# 2. The directory /etc/emacs/site-start.d already exists at the time of
|
|
# cmake invocation (not at the time of make install). This is
|
|
# typically true if emacs is installed on the system.
|
|
|
|
# Note that symbol IDs are not preserved through a load/edit/save operation.
|
|
# This may change if the ability is added to spirv-as.
