<p>Hi Don,</p>
<p><br>
</p>
<p>thanks, but that isn't completely what I want.</p>
<p>THe way you explain it, I have to first build llvm an install and
then seperately my project. <br>
</p>
<p>But that isn't what I want. I want to build it together as one
thing. In the Rust Compiler they have llvm as a submodule in src
folder. I don't know how they do it but they don't use CMake so it
won't really help to look it up. And I want to only build those
llvm libraries I will need for my project. <br>

I am sorry but I really am not good with cmake yet.<br>

I made one mistake I used MODULE instead of CONFIG in
find_package.<br>
<br>
But even with CONFIG I doesn't work for me.<br>
<br>

Here part of the cmake output in terminal:<br>

Could not find a package configuration file provided by
"LLVM" with any of<br>
the following names:<br>
<br>
LLVMConfig.cmake<br>
llvm-config.cmake<br>
<br>
Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH
or set<br>
"LLVM_DIR" to a directory containing one of the above
files. If "LLVM"<br>
provides a separate development package or SDK, be sure it
has been<br>
installed.<br>
<br>
<br>
-- Configuring incomplete, errors occurred!<br>
See also "/home/timoo/Schreibtisch/buil<wbr>d/CMakeFiles/CMakeOutput.log"<br>
<br>
<br>
I added the PATHS to find_package becouse the command must
find the files.<br>
<br>
In the llvm/cmake/modules dircotry are:<br>
<br>
LLVM-Config.cmake (instead of lower case) and<br>
<br>
<a href="http://LLVMConfig.cmake.in" rel="noreferrer" target="_blank">LLVMConfig.cmake.in</a>
(.in added at end)<br>
<br>
<br>
So what must I do?

Hi all.<br>
<br>
<br>
I want to use llvm in my project and I want to make
llvm a git submodule in my project.<br>
<br>
<a href="http://llvm.org/docs/CMake.html#embedding-llvm-in-your-project" rel="noreferrer" target="_blank">http://llvm.org/docs/CMake.htm<wbr>l#embedding-llvm-in-your-proje<wbr>ct</a><br>
<br>
At this in the documentation it claims to describe how
to embed llvm into a project. I tried it that way but
it doesn't work, because there isn't any
findLLVM.cmake in the llvm/cmake/modules directory
anymore (i don't know if there was one in the past).<br>
<br>
<br>
Can someone tell me how to do it now.<br>
<br>
<br>
