問題描述
demo指路：https://github.com/EdVince/Stable-Diffusion-NCNN
在Linux端使用cmake編譯文件時(shí)，
cd x86/linux
mkdir -p build && cd build
cmake ..
make -j$(nproc)
執(zhí)行cmake ..命令，報(bào)錯(cuò)：
CMake Error at CMakeLists.txt:14 (FIND_PACKAGE):
By not providing "Findncnn.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "ncnn", but
CMake did not find one.
Could not find a package configuration file provided by "ncnn" with any of
the following names:
ncnnConfig.cmake
ncnn-config.cmake
Add the installation prefix of "ncnn" to CMAKE_PREFIX_PATH or set
"ncnn_DIR" to a directory containing one of the above files. If "ncnn"
provides a separate development package or SDK, be sure it has been
installed.
-- Configuring incomplete, errors occurred!

問題原因
拉取ncnn的代碼庫（包括submodule）后沒有build and Install，所以cmake時(shí)找不到對(duì)應(yīng)的包，只需要讓它找到對(duì)應(yīng)的包即可，分為2步：
- 生成對(duì)應(yīng)的cmake文件（
ncnnConfig.cmake、ncnn-config.cmake） - 設(shè)置環(huán)境變量（
CMAKE_PREFIX_PATH或者ncnn_DIR）
解決方法
-
build and Installncnn
需要執(zhí)行以下命令：
cd ncnn
mkdir -p build
cd build
cmake ..
cmake之后繼續(xù)在build目錄下，執(zhí)行：
make install
發(fā)現(xiàn)彈出的信息中有：
這其中的ncnnConfig.cmake、ncnn.cmake就是我們需要找的包，找到上一級(jí)目錄，右鍵復(fù)制路徑
- 設(shè)置環(huán)境變量
export ncnn_DIR=/home/gaoyi/ldm-ncnn/Stable-Diffusion-NCNN/ncnn/build/install/lib/cmake/ncnn
這個(gè)環(huán)境變量就是上一步復(fù)制的路徑
- 重新運(yùn)行
cmake
cmake ..
