Looks like '+' is not a valid character for the target name.
Specifically, cmGeneratorExpression.cxx does not have it as part of the
regular expression to match target names: (line 23 on)
this->TargetInfo.compile("^\\$<TARGET"
"(|_SONAME|_LINKER)" // File with what
purpose?
"_FILE(|_NAME|_DIR):" // Filename component.
"([A-Za-z0-9_.-]+)" // Target name.
">$");
(In case you're unfamiliar with regular expressions, that + is just to
denote 1 or more of the things between the [ and ] . )
I tried adding + to that list, but I'm not sure how (if it's possible)
to escape it (and it resulted in a regular expression compile error
(runtime)). I'd suggest using something else instead of a + in your
target name.

Subject: [CMake] $<TARGET_FILE:tgt> in the add_custom_command()
Hi,
If the project name has a symbols "-" or "+" the $<TARGET_FILE:tgt> in
the add_custom_command() return Error: "Error evaluating generator
expression"
For example:
SET ( PROJECT_NAME "00010-Liquid+Gas_as_capture " )
set ( SRCS_MAIN_CPT main.c )
add_executable ( ${ PROJECT_NAME } ${SRCS_MAIN_CPT} )
add_custom_command ( TARGET ${ PROJECT_NAME } POST_BUILD
COMMAND "$<TARGET_FILE:${
PROJECT_NAME }>"
ARGS "$<TARGET_FILE_DIR:${
PROJECT_NAME }>/110.cnf"
COMMENT "Running cpt.exe..."
)
When I run the CMake I received the following error:
"CMake Error at problems.rt.Cmake:114 (add_custom_command):
Error evaluating generator expression:
$<TARGET_FILE:00010-Liquid+Gas_as_capture>
Expression syntax not recognized."
Is this a bug or some syntax limitation?
Regards,
Alexey
