cmake 2.8 shows errors when configuring, I can clean up sopvop/ptexutils@288981f2 commit and make a pull request.

Ptex: v2.4.1 static & dynamic link
OIIO: v2.2
freeglut: v2.8.1-6

LHS is on Ubuntu，RHS is on Windows. Maps cannot be displayed on Ubuntu.

Have troubles with compiling ptexutils for Windows, MSVC 2017
Compiled all dependencies with vcpkg. All project have the same errors in converting std::string to Ptex::v2_3::String

Do somebody have any suggests, what it could be?

With the shift to storing the API version in PtexVersion.h, the section where it checks for API version in (https://github.com/wdas/ptexutils/blob/56b32c1e853fbe750e826b3b9e2e61863b5755aa/cmake/FindPTex.cmake) will fail because it only checks in Ptexture.h, and will come up with an empty string (the actual error comes when trying to perform the subsequence REGEX MATCHALL on an empty string). It should probably check both headers to support backwards compatibility.

I have finally spent some time and cleaned up my small ptex-tools project.

Currently there are two tools, one for merging ptex textures into one, to make dealing with
cases when you have multiple meshes with same material a bit easier. And tool for reversing winding order in ptex texture, helps when you need to render both alembic cache with renderman procedural and rms exported geometry.

I think it would be nice to merge these tools into ptexutils.

Exposing ptexutils tools not only as executables, but also as a library
and possibly python module (as ptex-tools does).

Merging future tools (besides viewer, it adds GL dependency) into single executable, with interface like git has. That would make using statically linked ptex library less painful. Statically linked executables are somewhat easier to deploy by just dropping into shared NFS folder. And yes, ptex-tools does that ;)
