System Information
Operating system: Linux-4.15.0-136-generic-x86_64-with-glibc2.27 64 Bits
Graphics card: Mesa DRI Intel(R) HD Graphics 5500 (BDW GT2) Intel Open Source Technology Center 4.6 (Core Profile) Mesa 20.0.8

Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-03-24 17:47, hash: 9ac7946dd0
Worked: (2.92.0)

Short description of error
When I try to compile any OSL shader I get an error below

blender-2.93.0/2.93/scripts/addons/cycles/shader/stdcycles.h:31:10: fatal error: 'stdosl.h' file not found
#include "stdosl.h"
         ^~~~~~~~~~
Error: OSL script compilation failed, see console for errors

I tryed with this OSL shader on manual

shader simple_material(
    color Diffuse_Color = color(0.6, 0.8, 0.6),
    float Noise_Factor = 0.5,
    output closure color BSDF = diffuse(N))
{
    color material_color = Diffuse_Color * mix(1.0, noise(P * 10.0), Noise_Factor);
    BSDF = material_color * diffuse(N);
}

Exact steps for others to reproduce the error
after I added a new text file inside Blender with code of simple OSL I added a script node with the OSL shader but this isn't compiled.
attached .blend file
Simple_material_OSL_293_version.blend

I can verify that this happens in the alpha builds available on https://builder.blender.org/download/.

The install process is supposed to locate those headers from the OSL library's installation, however, the path that is resolved by FindOSL.cmake is libdir/osl/shaders, when they are in libdir/osl/share/OSL/shaders since the latest library update (rBL62577 for Linux, but is the same for other platforms).

My CMake skills are apparently lacking so I am going to let anyone of the platform maintainers fix this.
