Julia_VERSION_INCLUDE-NOTFOUND

[timholy]

I have a source build of Julia. I'm trying this:

tim@diva:~/src/libcxxwrap-julia-build$ cmake -DJulia_PREFIX=/home/tim/src/julia-1/julia ../libcxxwrap-julia
-- Adding path /home/tim/src/julia-1/julia to search path

It may be worth noting that /home/tim/src/julia-1/julia launches Julia successfully.

For me '/home/archit/Downloads/julia-1.3.1/bin/julia' launches Julia and '/home/archit/Downloads/julia-1.3.1' was the correct directory to use. With the wrong directory for '-DJulia_PREFIX' I had the same error.

I get the same error if I eliminate the julia, i.e.,

tim@diva:~/src/libcxxwrap-julia-build$ cmake -DJulia_PREFIX=/home/tim/src/julia-1 ../libcxxwrap-julia
-- Adding path /home/tim/src/julia-1 to search path
-- THIS BRANCH
CMake Error at FindJulia.cmake:32 (file):
  file failed to open for reading (No such file or directory):

    /home/tim/src/libcxxwrap-julia/Julia_VERSION_INCLUDE-NOTFOUND
Call Stack (most recent call first):
  CMakeLists.txt:17 (find_package)
...

However, it works for me if I point it to a binary download I have on my hard drive. So my guess is that this package assumes binary but not source builds of Julia.

Sorry for the late reply, there are two options that should work for a source build:

cmake -DJulia_PREFIX=/home/tim/src/julia-1/usr ../libcxxwrap-julia

or

cmake -DJulia_EXECUTABLE=/home/tim/src/julia-1/julia ../libcxxwrap-julia

Feel free to reopen if that doesn't solve it, of course!

Sorry, I seem to have missed your reply. Works great! I seem to have missed the line about "directory containing the bin and lib directories." I will submit a PR to amplify this a bit, but feel free to close it without merging if you don't think it's a net improvement.
