Hello,
I have a custom target which runs a command to generate
a C source file say test1.c
ADD_CUSTOM_TARGET(TestGen ALL
COMMAND genExec ${PROJECT_SOURCE_DIR}/Main.java
DEPENDS ${PROJECT_SOURCE_DIR}/Main.java
)
And I have a custom command that moves the generated *test1.c *
to a new directory inside the build directory.
ADD_CUSTOM_COMMAND(
TARGET TestGen
POST_BUILD
COMMAND mv
ARGS ${PROJECT_BINARY_DIR}/test1.c ${PROJECT_BINARY_DIR}/tests/
)
Each time I run make, the custom target is run (since custom targets are
always
out-of-date). But I want to avoid moving the new test1.c generated each time
if build/test1.c is the same as build/tests/test1.c since there are other
targets
like add_executable and add_library later in the CMakelists file that are
re-built
each time since they depend on test1.c
I tried cmake -E compare_files inside execute_process, but it would not be
executed before the custom command.
I tried cmake -E compare_files inside a custom command as well, but that
would give an
error and halt the make process if the files differ.
I want to avoid re-building later targets that depend on test1.c.
Thanks
Ajay
