-----------
23+
24+
This module is intended to detect Julia as a package.
25+
26+
Imported Targets
27+
^^^^^^^^^^^^^^^^
28+
29+
``Julia::Julia``
30+
Julia Package, if found
31+
32+
Result Variables
33+
^^^^^^^^^^^^^^^^
34+
35+
``JULIA_LIBRARY``
36+
Julia shared library
37+
``JULIA_EXECUTABLE``
38+
Julia REPL executable
39+
``JULIA_BINDIR``
40+
directory to Julia binary
41+
``JULIA_INCLUDE_DIR``
42+
directory that contains Julia.h
43+
44+
Usage
45+
^^^^^
46+
Use:
47+
``list(APPEND CMAKE_MODULE_PATH "path/to/this/file")``
48+
``find_package(Julia 1.7.0 REQUIRED)``
49+
50+
to make the Julia target available to your target through
51+
``"$<BUILD_INTERFACE:Julia::Julia>"``
