代码：
#include <pcl/io/pcd_io.h>
#include <pcl/filters/passthrough.h>
int
main(int argc, char** argv)
{
pcl::PointCloud<pcl::PointXYZ>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZ>);

if (pcl::io::loadPCDFile<pcl::PointXYZ>(argv[1], *cloud) != 0)

return -1;
}
pcl::PassThrough<pcl::PointXYZ> filter;
filter.setInputCloud(cloud);
filter.setFilterFieldName("z");
filter.setFilterLimits(0.0, 2.0);
filter.filter(*filteredCloud);
}
Cmakelists1.txt :(支持连接到matlab引擎） Cmakelists2.txt :(不支持）
当我使用Cmakelists2.txt构建代码时，我没有错误 但是当我使用Cmakelists1.txt构建代码时，我得到了一个巨大的未定义引用错误列表。 Cmakelists1.txt是Cmakelists2.txt的超集，所以无论2的构建都应该用1构建
代码是极简主义代码＆amp;为清楚起见，我删除了matlab部分。 有人可以帮忙吗？
