Windows Compilation Issue (Boost Related) #265

Open SimonCSmith opened 2 years ago

SimonCSmith commented 2 years ago

I've compiled the core Blackbird library (1.1.1), USD (21.11) and all dependencies (including static Boost 1.77.0) for these under VS2019 using CMake. With everything in place I am trying to build hdBlackbird and i'm having issues with CMakeGUI generating the project file.

I am getting a slew of Target "xxxCycles" links to target "Boost::xxxx" but the target was not found (usdCycles, ndrCycles etc).

Am I missing something, or is something missing from the CMake setup to locate Boost? I tried adding BOOST_DIR but that did not help - I'm sure it just needs to knowe where to find them, but i'm no export with CMake i'm afraid.

It has been a while, but CMake included in this project does not locate boost. Usd exports configuration file and then cmake searches for it here.

Ah, so there must be something wrong with the latest Pixar USD builds regarding exported cmake configuration files maybe. It finds the USD install OK once USD_ROOT is set (it locates the isdGenSchema and pxr_DIR variables OK). The configure step works just fine, but it's the Generate that is failing.

The cmake line that causes the error is: add_library(usdCycles SHARED ${USD_CYCLES_SCHEMA_SOURCE_OUTPUT})

I've also added BOOST_USE_STATIC_LIBS as well (as that's how I have boost built) but that did not help either (along with BOOST_DIR).

Is there any way to force cmake to generate the Blackbird project files anyway so that I can get some vcxproj files out that I can manually fix linkage for in Visual Studio? When CMake goes wrong it's seems such a dark art to get working ... so very frustrating every time it happens!
